Got stuck recently during a remote gig installing CentOS. Vanilla install failed due to a hardware error and had to be reinstalled but unlike the earlier versions there wasn’t a clearly defined path to delete existing partitions. So here is what we did;
Installation destination:
- Custom partitoning, create automatic partitions will prompt that there is not enough free space
- Click Done to go back
- Select Automatic partition, click Done
- Click the recover free space option on the Error prompt window
- Delete all exiting partitions (or as needed)
- Click preserve to save changes
- Click Done to go back
- The Disk free space displayed near the bottom has increased
That’s it. You can now proceed with the usual installation steps.
